BLUE JAY. 109 



tressed cry from one bird will luring all the others in 

 the neighljorhood. 



The usefulness of the Blue Jay seems to be in eating 

 the moth which is destructive to grapes, and in plant- 

 ing trees. He hides nuts and acorns in holes in the 

 ground and many of them sprout and grow, so that 

 we are indebted to him for some of our finest forest 

 trees — oak, chestnut, and beech. 



Jays build in trees, from ten to fifteen feet above the 

 ground, generally where a branch joins the trunk. 

 The eggs, 4 to 6, are thickly marked with cinnamon- 

 brown.
